Colt. 1911. The purist's pinnacle. My love affair with John Browning's masterpiece began before I was old enough to purchase one. Just something about these that turns the old crank.
Like most 'gun cranks' (that's how the old guys referred to those such afflicted when I was a pup many decades ago) I have, to my dismay, shame, and regret let several 70 Series original specimens slip through my collection and move on to finance something else new and shiny at the time . . . because after all, "they're all over the place and I can get one anytime I want to replace it !". Until the rest of the shooting world caught up and that statement was no longer true.
I blame Jeff Cooper and the advent of practical shooting competitions for revealing to the Average Joe what those of us who tumbled onto it early in life already knew - the 1911 (to us) was the best overall large caliber semi-auto ever made. The haters are gonna hate and disagree, but it's hard to deny that anyone has found anything better on that scale. The deniers will point to all their favorite plastic sissy pistols ( that was a
joke for those who got offended

) but the mountain of empirical evidence is hard to deny.
Colt is still the Cadillac of 1911's despite all the other usurpers who attempt to dethrone that notion. Having said that, the genius of John Moses Browning has been recognized by so many other copy cats as to destroy all argument to the contrary that the 1911 is still in contention for kingship.
I recall a conversation I had back in the 70's with a S&W field rep when I only half jokingly asked him when S&W was gonna produce a proper functioning thumb safety that was swept down with the thumb as the gun came up to presentation from the holster. And when S&W would give in and produce their own version of the 1911. He replied snidely and with conviction, "
That's NEVER gonna happen!"

Ah so . . . . . .
Anyway, I still love my Colt's and have tried to make amends for the 'ones that got away', but the love of the 1911 for me transcends brands. Kimber, Springfield, S&W, even RIA's . . . just gotta love 'em . . . .
